What are High-Frequency Welding Machines in Hall Production
High-frequency welding machines are key equipment in the production of tent hall covers. HF technology (27.12 MHz) creates welds with strength exceeding traditional thermal welding methods. Unlike hot air welding, where material is joined superficially, HF technology integrates the molecular structures of the material, creating a connection indistinguishable from the base material.
Applications in Tent Hall Production
FIAB welding machines are used to produce all key hall elements:
- Roof covers – welding strips of PVC material 650-900 g/m² for hall roofs with area of 500-5000 m²
- Side walls – production of tarpaulin panels with windows and doors
- Curtains/gates – welding sliding hall closure elements
- Piping and tunnels – application of fastening systems to steel structure
- Reinforcements – welding reinforcing strips under clamps and frames
- Transparent windows – integration of transparent film with tarpaulin material
- Connecting elements – production of corners and structural connections
FIAB Welding Machine Portfolio
For small and medium tarpaulin production, FIAB 500, 860, 960 machines with 5-8 kW power and electrode length of 700-800 mm are used. For industrial production, FIAB 1400 (13-26 kW, electrode up to 1500 mm) is dedicated, available in stationary and mobile versions. Mobile FIAB HPS-MINI enables repairs and welding directly on the structure.
Why HF Welds are Better
PVC material welded with HF method is characterized by:
- Tensile strength – welds stronger than the material itself
- Weather resistance – resistance to UV, frost (-40°C), rain, wind
- Tightness – no micro-leaks, complete waterproofing
- Durability – lifespan of 15-25 years in year-round operating conditions
- Safety – no adhesives and solvents
Hall Cover Production Process
- Cutting – cutting PVC material according to design
- Strip welding – joining sheets with overlap (30-50 mm)
- Reinforcement application – welding strips under clamps and fastenings
- Piping welding – mounting fastening systems to profiles
- Window mounting – integration of transparent film
- Finishing – mounting eyelets, clamps, locks
- Control – tightness and strength testing
Materials Used in Halls
- Coated PVC (650-900 g/m²) – standard for year-round halls
- Architectural materials (1100-1300 g/m²) – large roof spans
- Transparent films – windows and skylights in halls
- Flame-retardant fabrics – sports and event halls
Types of Welds in Hall Production
- Overlap weld – basic strip joining (30-50 mm width)
- Tunnel weld – pockets for beams and structures
- Reinforcement weld – application of strips under clamps and frames
- Piping weld – mounting fastening systems
- Window weld – integration of transparent elements
Electrodes for Tent Hall Production
- Lamellar electrodes (700-1500 mm) – linear welds
- Tunnel electrodes – pockets and tubes
- Double electrodes – simultaneous welding of two lines
- Curved electrodes – arches and contours
Efficiency and Economics
HF welding machine compared to traditional methods:
- Speed – 10-15 m/min linear weld
- Efficiency – 200-500 m² of cover daily (1 operator)
- Time savings – reduction of 60-70% vs manual welding
- Quality – 100% parameter repeatability
- Durability – minimal machine maintenance
